SPECIFICATION forming part of Letters Patent No. 415,545, dated November 19, 1889.

Application filed January S1, 1889. Serial No. 298,229. Y (No model.)

To all. whom, it may concern:

Be 1t known that LVILLIAM MATHER, en-

gineer, a citizen of England, residing at Salford Iron lVorks, Manchester, in the county of Lancaster, England, have invented a new and useful Improvement in Apparatus for Treating Textile Materials with Liquids, Gases, or Vapors, of which the following is a specification.

In my patent dated August 4, 1885, No. 323,819, and in my later patent, dated J anuary 5, 1886, No. 333,876, l described apparatus for treat-ing textile materials with liquids, gases, or vapors for various purposes, such as soaking,boiling,or dyeing. That apparatus consisted of a keir or vessel like a horizontal cylindrical boiler closed at either end or at each end by a wedge sluice-door, and having in it rails to receive trucks ciontaining the material to be treated, and pipes i'or supply, discharge, and circulation of the fluids to the action of which the material in the trucks was subjected. j

The objects of my presentinvention are to provide novel and eliicient means for utilizing the fluid-pressure within the keir for the purpose ot' securing atight joint between the door and the end ot' the keir or vessel, and, further, to provide novel mechanism for effecting a tightclosure of the door against the outward pressure of the gases and luids within the keir. j

The objects of my invention l accomplish by the combination ot' devices hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is a longitudinal section of a keir accommodating two trucks with a wedge sluice-door at one end. Fig. 2 is a sectional plan view ot' the same. Fig. 3 is a part transverse section on the line e' e, Fig. 2. Fig. l is an elevation of the abutment and guide in which the wedge-door slides. Fig. 4 is a section on a larger scale of part of the end ot the keir, showing the packing of the door. Fig.

5 is a sectional plan view, and Fig. G an eleJ vation, of the gear for tightening the door. Fig. 7 is an elevation showing the recess of the door in which the tightening-segment works; and Fig. S is an enlarged sectional dctail view ot' the mouth of the keir and its door, showing the packing-rings.

The keir A is made with a liat end, against which the wedge sluice-door B is pressed by sliding in the adjustable abutment B2 This door consists ot a bent plate B', inclosed in a cast-frame B2, having an inclined back. At the back of the door B is an adjustable framing 4or abutment B3, presenting a groove in which the sides of the trame B2 'can slide, the abutment B3 having at its back an inclination corresponding with that of the frame As the sluice-door Bis of considerable size and the fixed incline-framing 153, which forms the abutment, when it is closed should force itagainst the end of the keir with uniform pressure throughout the wh ole circumference, I secure the framing B3 to the flange at the end of the keir A by a numberof bolts E4, as shownV in Figs. l and l, these bolts being inclosed in tubes, between which are distancepieces B5, between the end of the keir and the framin E3... The lengt-hs of these distancepieces are adjusted by trial-that is to say, the door being closed the keir A is charged with liquid and subjected to internal pressure. Itis observed where leakage takes place between the door and the keir, and the distance-pieces for the bolts adjacent to the leaking-place being shortened a little, by filing or otherwise, the bolts are again tightened. This is repeated until the leakage is suppressed.

From the top of the frame B2 a chain C passes over guide-pulleys C to a cylinder D loaded with weights D sufficient to overbalance the door B. This cylinder works on a tubular plunger E not necessarily requiring packing, as the movement of the cylinder is only occasional and momentary, and a little leakage is not seriously objectionable.

Vith the bottom of the tubular plunger E communicates a pressure-vessel F, having at its top a steam-pipe F and gage-cock F2. Vhen the door B is raised, the cylinder D bcing then down on the plunger E, the vesselF is charged with water up to the level of the gage-cock F2. 7When it is desired to lower the door B, the gage-cock F2 is closed and steam is admitted by the pipe F to press on the water in the Vessel F. The pressure trans- IOO bears a metal ring A2, held in position byl` screws A0, the heads of these screws overlap-- ping the thinned edge of the ring A2, but al-v lowing it to be pressed up toward the face of the keir. seen that the elastic packing-ringA projects somewhat from the groove in which it sets,

so that it will be exposed to the Huid-pressure i within the keir, an d be thereby forced tightly v against the inner face of the keir and form a tight joint therewith. At the same time the Huid-pressure exerted on this elastic packingring A"causes it t expand and press tightly against the metal ring A2, thereby forcing the latter closely against the closed door B, andas this metal ring A2 is of greater width than the ring A and projects inward beyond the same it will also be' subjected on its innerface to the direct effect ot' the Huid-pressurewithin the keir. der the direct action of the fluid-pressure on the ring A2 and the outward pressure of the expanded elastic packing-ring A the metal ring A2 will be forced so closely against the keir and its door as to forni a tight joint that will effectually prevent leakage. Then the door is fully closed, it presses the ring A2 toward the keir, the elastic ring A is forced toward the inner face of. the keir by the fiuidpressure and at the same time expanded or pressed tightly against the inner face of the l metal ring A2, and the latter, under the action of the fluid-pressure, is pressed tightly against the keir and the door B, so that itis obvious that a tight joint will be formed all around the mouth of the keir.

As the descent of the door B due to gravity is not quite sufiicient to insure the required wedging action, gearing is employed to draw down the door B alittle farther than it would descend of itself, and to hold it down, notwithstanding the relief of the hydraulic pressure in the cylinder E. rThis gearing consists of a lever L, with reversible pawl' L', engaginga square-toothed ratchet-wheel L2, which can be turned by working the lever L as a `ratchet-brace in either direction, according as the pawl L is turned the one way or the other. On the axis of the ratchet-wheel L2 is fixed an eccentric disk M, having projecting from its face a segment M.

In the lower framing of the door B is formed a recess, as shown in Fig. 7, having through its bottom rib at one side a slot M2 Wide enough to allow the segment M to pass through it. The disk M being turned so that the segment M stands in the position indicated by the dotted lines M2, Fig.7, the door By referring t0 Fig. 4 it will be` It will thus be seen that un- B is lowered, the slot M2 passing the segment M2. rlhe disk M is then turned so as to bring the segment M over the lower rib of the .recess, the eccentricity of the segment pressing this downward, and thereby further wedging down the door and holding it down. Vhen it is desired to raise the door B, it can iirst be slacked by turning the segment M so as to bear up against the top rib of the recess, so slightly raising the door B, and then on turning the segment back to the position M3 and relieving the pressure in the hydraulic cylinder D by opening the cock F2 the loaded cylinder D descends, pulling up the door B.

Having thus described my invention, what I claim isl. The combination, with a keir and its door, of a packing composed of an elastic ring and a metal ring located in the mouth of the keir at the inner side of the door, and means for closing and securing the door, whereby the fluid-pressure Within the keir will force the said packing against the inner face of the keir and its door and form a tight joint around the mouth of the keir, substantially as described.

2. The combination, with a keir and its door, of a packing composed of an elastic ring and a metal ring interposed between the mouth of the keir and its door and' exposed to the action of the fluid-pressure within the keir, whereby said packing is caused to form a tight joint around the mouth'of the keir, substantially as described.

3. The combination, with a keir and its door, one of said parts being provided with an annular groove, of an elastic ring located in and projecting from said groove, a metal ring bearing against the end of the elastic ring and against the inner face 0f the keir, and means for closing and securing the door, whereby a tightjoint is formed by the fluidpressure within the keir acting in said rings and forcing them against the inner face of the keir and its door, substantially as described.

4. In combination with the Wedge sluicedoor of a keir, a ratchet, reversible pawl and lever, an eccentric disk with projecting segment, and a recess in the door with slot for passage of the segment, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two su-bscribing witnesses, this 12th day of January, A. D. 1889.
